"Watching sport is supposed to be family-friendly and by banning the promotion of live betting odds on televisions and at sporting grounds, the government is ensuring that sport continues to be family-friendly into the future," Ms Franks said in a statement on Tuesday.

She said the explosion in online betting was having a devastating impact, particularly on young men.

"It's little surprise when they are being courted so aggressively with gambling front and centre of sport, when it should be the footy that is the main game," Ms Franks said.

Ms Franks noted Greens Senator Richard Di Natale had a federal bill that would ban all gambling ads before 9pm, and prevent the broadcast of live odds during sport and sports-related programs.
